TYPE-WRITER DUPLICATIN G MECHANISM.

`To aZZ uwln it may concern.'

Be it known that I, Marcus C). ANTHONY, a citizen of the United States, residing at New York city, county of New York, State of New York,v have invented an Improvement in Typeelvriter Duplicating Mechanism, of which the following description, in connection with the accompanying drawing, is a specification. like characters on .the drawing representing like parts.

This invention relates to repeating or duplicating mechanism for ty-pewriting machines and comprises means whereby a word, a line, or a series of lines may be typewritten in the usual manner or may be set up on mechanism which may thereafter be 'caused to actuate the type bars in the order in which they were first struck to reproduce the subject matter Originally Written or setup. y

Frequently in commercial work it is desirable to write certain subject matter 'and repeat the same an indefinite number of times and during the time such repetltion is being accomplished to interrupt the duplilcation to typewrite other subject matter dif fering therefrom and when the latter has .been completed to return to the repetition of the subject matter originally Written. As a 'specific instance of the utility of such a mac 1 ine mention maybe made of the typefvriting of pin tickets adapted to `be attached to artlcles of merchandise oi'ered for sale in stores. In writing pin tickets it is frequently necessary to write several hundred of one kind and but one or two of an-V other and it is also desirable oftentimes to Write. a `few tickets'ibefore the duplicating.

mechanism has completed illinga large order. It is'therefore desirable that a machine beprovidedfwith means inwhich the subject matter adaptedto be printed on a' large number of tickets may be setup and the dui v plication proceeded with at will, and also.

thatthe machine be provided with means whereby the mechanism may be rendered temporarily inoperative to permit the' Wrltr l, f Vingof'tickets of another character.

In the preferred 'form o f machine embodied in this invention which 1s disclosed herein an ordinary typewriter is utilized,

repeatingl mechanism being placed beneath.

the same in which the subject matter'written on the rst card is set up bytmeans of actua tors positioned upon the surface'of a rota- Speccation of Letters Patent.

table drum, said actuators being adapted to coperate with electrical contacts during the subsequent revolutions of the drum to energize solenods connected with the .keys of the typewriting machine to cause the repetition of the subject matter set up in the order in which the keys were originally struck.

One of the objects of this invention therefore is to produce a duplicating mechanism for a typewriting machine which will re-V vsubject matter is being written without disarranging the repeating mechanism 4so that the duplicating Operation may .be resumed without resetting the subject matter. l

Another object `of the invention is: to provide means for rotating the repeating mech anism intermittently to receive and position.

the'actuators representing the subject matter originally Written and to providemeans Wherebjy the drum Will be automatically stopped upon thecompletion of a sing-le rotation. 1 r y Another object of the invention'is to provide an electrically actuated key operating mechanism adapt-ed initially to depress the key with a comparatively slow movement yand to end the stroke with an accelerated movement.I

VAnother object ofthe invention is to'provide a support for' the card or pin ticket which is to receive the4 subject matter tolbe Written with electrically operated means for raising thesame for differently spaced-lines of typewriting.

which may be electrically operated from the yline spacing key of the typewriter and* Which means may'aliso be actuated by' mechanism controlled fromA the' repeating drum; v

hsillustrated in the` drawing the writing machine comprises a -usual construction in which thekey levers 't5- are pivotaad upon a. 7 'at the rea-r of the machine and are provided with a-.downwardly offset por? tion'S which has been utilized in the present constructionl as a 'means foroperating the settin up mechanism as will'hereina-fter be I usual bell-'crank lever 9, one-'arm o-which is connected 'to the slotted end of tlie t 4pe bar 10 so thatupon thedepression of the ey ,the type barvvill be actuated in the usual manner. The .usual typewriter 4escapem'ent for releasing the carriagel step by step-is present in the machine a though not shown 1n the drawings.

. Mounted' upon the face 1 beneath thef l typefvriting mechanism is a. traveling repeating mechanism 'which is preferably. Vin

The drum.' heads are connected-by "al" Vspfcin'g sleeve 18 and carry between them an annular' member '19 which -is provided with. a series-of ed actuators 21', the' stems 22fof which are I provided. with 0ppositely"'disp0se d recesses `referees- 23 which receive guide plate zgisecured to the ends of the partitions 254 which separate .the radial slots 20.

As is illustrated in Figs. at and 5 each actuaton is 4'retained normally in position at the left end of the drum by a serrated rack QGIwhich passes through an aperture 9,7 in the head ot' the actuator 21, the rack 2G being normally held projected toward the periphery of the drum and in' locking engage ment with its actuator by springs Q8 located beneath its ends. The stem 22 of each actuator is connected to one end of an elastic member preferably a spiral spring 29 which extends around a pulley 30 upon a ring 31 clamped in coperating grooves in the head 15 of the drum and a supplemental head It will thus be observed that the lactuators` vare constantlyl under the tension of the springs 28 which tend to slide them longitudinally of the drum, and upon their release from engagement with the rack 26 they will slide freely along the surface of the drum and therefore may be positioned beneath the type bars by suitable arrestingmechanism actuated from the type bars.

The actuators' when 4thus positioned by the type bars are adapted to contact with silient members 33 ofelectrical contacts located `upon ,thebase 1 of the machine andf'loy depressing the members 33 against their cooperating members 34 to complete an electrical circuit through the solenoids 35"'causing the cores 36 ofv such solenoids to bede# pressed and through suitable connection with the key levers 6, as by hooks 37 em bracing said levers, wil-l cause the actuation of the type bars to Vduplicate the subject member set up in the drum.

In order to produce a staccato stroke of the type bar during the repeatingoperation like that which is given by the normal operation of the type keys mechanism is provided which is adapted to impart a rela- .tively slow initiahlno'vement to thetype bar which is accelerated as the type approaches the platen and isimmediately released upon thejco'mpletion ofthe stroke.

ferred form illustrated herein the lower end Vof the solenoid is 'provided with an4 armature 438 of cylindrical form which exu tends upwardly within the hollow core of the coil to, or nearly to, the point reached by. the lower end lof the solenoid core 3G when the type key is depressed. When the solenoid is energized the armature 38 becomes in effect an electro-magnet and as the lcore o-f the solenoid is draw-n down it enters the field of the armature magnet and is drawn .down thereby with an accelerating force in vaddition 'to that of thesolenoid itself. `When the type bar has'nearly e01n. pleted its Vstroke the solenoid circuit is aui' tomatically broken by the passing of the actuator from thel spring contact, they sole- Vvnoid y1s conotfqnentlyydiaenga ed and the. type bar permu'tedfild reboiin in subsi-M);A

It will be 'obvious that the electric circuits which operate the. solenids to cause the duplication must be rendered inap-- erative during the setting'up operation andl the means whereby said circuits are thrown into'or out of voperation will be pointed -out hereafter in connection with the' de' scription of the diagrammatic illustra-tions" of the electric circuits exhibited in* Ffgsffl and 17.

tending laterally from the lever 82 which carries the paivl 83. ,An additional pawl 88 ma also be pivoted to the top of the standai' .12 to' engage the teeth of the ratchet Wheel 84 to insure the same against baclrward rotation when the drum is being rotated by electrical power in the duplication of the subject matter originally Written for it is to be understood that the drum is actuated bythe solenoid 80 only while the actuators are beingpositioned upon its surface.

When the subject matter has been set up upon the drum in the manner heretofore described the drum is given a positive revolution to duplicate the same by means 0f an electric mot-or 90 -which is attached to the base 1 of the machine and is provided with a Worm 91 adapted to engage the gear 92 mounted upon the countershaft 93 directly beneath. a shaft 9-1 (sce Fig. 12) Which constitutes an extension o1? the drum shaft 16. The shaft 93 is provided with a smaller gear 95 which engages a gear 96 -Which is loosely mounted upon the shaft 91.

Suitable clutches. are provided as will here inaftcr be described .for connecting' the gear 80 96 with the shaft 94 and also for connecting the shaft 9i with the'hollon shaft 16 of the drum and suitable stop mechanism is Valso provided. whereby the shaft 94. may be released from its engagement with the electrically operated vdriving mechanism and lthe drum 'simultaneously caused to he arrested from further movement.

' The clutch mechanism which connects the end of the shaft .16 'with the adjacent end 40 of the shaft 94 comprises a ring 97 rigidly secured -to said shaft` 16 having a pawl 98 normally pressed by a spring 99 into enyga ement with a collar 100 suitably attac ed to the end of the shaft 94 and hav- 45.. ing a shoulder 101 adapted to'be engaged thepawl 98. During the rotation of the drum by-the solenoid mechanism above de- .scribed While the actuators are being posii -tioned the paivl rides freely upon the collar 100. When however the drum is driven by .4 they electrically operated mechanism for dit plieating the subject matter set up the shoul .-clerlOll of the collar 100 engages the end ofthe paul-.98 and thereby impart-s rota- I 'ltion to .the drum in the same direction in which it was previously rotated by the soleincid mechanism.

i The clutch mechanism for connecting the electricallyperated dri-ving mechanism to theV sha-ft .-9 4 sarranged in the following rmannerr 'Dhe'gear,96 is revolubly mounted upon a? suitably journaled sleeve 104 which surrounds said shaft 94 and is adapted to 4 'be positively .connected therewith 4by means 66 of a half round barI 102 which passes usualtypewriter escape mechanism.

through a cylindrical groove 103 one half of which is in said shatt and the other half in said collar 104 s urroui'idii'lg said shaft.

The end ci the bar 102 is attached to a level.' 105 which normally is held by a spring 70 1.06 in position to positively connect the gear 9G with the shaft 91. the half round bar 1.02 when in this position heilig partly engaged b'y the shaft 94e and partly by the collar 104.. (Figs. 12 and 13.) 75

`When the motor therefor is thrown into operation it will positively drive .the gear 96 and through it the shaft 9-1 to rotate the collar 100 and through the pawl 98 rotate the drum as above described.

In order to stop the rotation of the drinn means are provided for releasing the half round bail 1.02 from its position engaging the shaft 91. and the gear 96 and at the same time braking the rotation of the drum. This mechanism comprises a lever 1.10 attached to a rod 111 journaled in suitable bearings 112r` 113 mounted in the base plate 1 saif'l rod having at its end a lever 1l 11 by means of which the lever 1.10 may be rocked into or out of the path of the lever 105. The lever is provided with an oiiset arm 115 connected by a li'nlry 116 to a vertical latch 117 l'iaving a shoulder at its upper end adapted to engage a stop 118 which is piv- 95 otally mounted on the toothedtlislr 8land retained b v a` spring normally against a pin 119 but adapted to yield upon engagement of the latch 11.7' until it comes in Contact with a pin 120 at which time the rota-ting loe drum 5 is arrested in proper position relative to the setting up mechanism. Y

Suitable mechanism is provided whereby the actuators may be restored to their normal position which in the device disclosed 105 herein comprises a head 121 (see Fig. l) having a series of attachedparallel rods 1522 extending through the drum head 14 and throng-h apertures in the stems of the actuators and provided with laterally project- 110 ing ends 123 adapted to limit the extreme movement ofthe latter. The head 121 is preferably provided with a handle .124 4by which it may be moved axially away from the drum head. When it is desired to re- .115 store the actuy irs to normal position at the left end of Lne drum the handle 124; is grasped by the operator and the head 121 moved axially thus driving out all the'rods 122 so that when their ends 123 reach posi 120 tioned actuatorsthe latter willV be moved with the rods until restored to normal position after Which the head 121 may be restored to its former position.

As ,has before been pointed out the trav- 125 erse of the carriag'e is controlled by, the

It is necessary however that automatic means be provided-for returning the carriage to its starting position during the duplicating opsothat when the drum is being rotated .circuit-for rotating the drum broken. y mechanism for accomplishing this result electrically to duplicate the subject matter originally set up' the card holder will be raised at the proper time to change the line.

In order to release the card holder and to permit it to return to its starting position after the subject 'matter of the card has been completed the drum 5 is provided with a pair of twin contacts located upon the last rack bar 26 of the series upon the-drum. These twin contacts serve toV actuate both the solenoids 172 and 173 simultaneously thereby releasing the dogs 17 5 in the manner aforesaid and permitting the card holder to drop to starting position.

. It will be observed from the foregoing description that in the manual operation of the typewriter and during the setting up of the actuators upon the drum the positioning of the actuators is accomplished through mechanical means, only the rotation of the 'repeating drum being effected by electrically `operated n iechanism.

Itwill also be noted that the carriage return key and the line key and the half line key each controlsy a separate circuit.

During the setting up operation it is of course' necessary that the circuits through the drum and the switches opera-ted thereby shall remain broken and inactive. When however the `drum is Vbeing automatically rotated by the motor 90 to duplicate the matter set up the last 4mentioned circuits` must be rendered active and the solenplid 1e comprises a switch member which is illustrated herein as located upon the standard. 4

11 at -the right end of the machine (see Fig. 1).

This switch which is shown in detail in Fig. 17 comprises two relatively rotatable members, preferably a cylindrical. member 190 and a disk 191 of insulating material to which is secured two sets of contacts 192,`

197 and 198 attached to its inner surface at substantially diametricall y opposite points,

but insulated therefrom, the member 19T being adapted to close the circuit of the drum operating solenoid through the contacts 192'and 193as illustrated in Fig. 17 and the member`198 to close the circuit of the key lever solenoids 35 through the contacts 194 and 195 when the switch imember 85 are rendered inoperative and vice versa.

It is necessary to provide means' whereby the circuit for the motor 9G which drives the drum shall be rendered inoperative during the setting up of the actuators and this is accomplished by providing the cylindrical switch member 190 with an insulating cover 199 having a bar Q00 adapted to bridge terminals 201, 5302 in the circuit of the. motor 90, these members being so arranged that when the switch 190 is in setting up position the circuit of the motor 90 will be disconnected as is illustrated in Fig. 17 and when the said switch is rotated to duplicating position, in which the bridge piece 198 closes the circuit through the contacts 19a and 195, the bridge piece 200 will lie across the terminals 201 and 202 as illustrated in dotted lines in Fig. 17V completing the circuit through the motor in the manner aforesaid.

It is also necessary that the circuits of the return andthe Yhalf line and line feeding mechanisms be removed from operative-conneet-ion with the circuits controlledv by the drum during the setting up operation and this is likewise accomplished by providing a series of pairsof terminals 203, 20aand 205 in these respective circuits which normally rest upon the insulated surface 199 of the switch 190. during the setting up operation but which may be bridged respectively vby bars 206, 207, 52,08 when the switch 190 is rotated to the position for causing the automatic duplication above referred to.

In Figs. 16 and 17 various circuits here' inbefore referred to are diagrammatically illustrated. In Fig, it A is used to distinguish the key lever for operating the carriage return, B the fever for operating the line key, C the lever te" operating the half line key, and F designates the circuit for actuating the solenoid which rotates the repeating drum it being understood that the Contact which is diagrammatic-ally. illustrated as projecting from the upper side of l key levers A, B, and C corresponds to the contact 56 which is carried by the bar 50 and is actuated by all of the 'key levers including the carriage return, the half line and full line levers.

In Fig. 16, M represents the sourceV of energy which may be a battery, a dynamo, or other source of electric supply and the key leversA B C and the drum are connected to a' common circuit G leading to `the battory or are grounded. Tracing thereforel thc circuit upon depression oi. key A the current' leads from the Vbattery through the groundtl and key A through the contacts 130;y 131 (see also Fig. 1) the line A to the i carriage return solenoid 130. thence through the line A to the battery M.

Upon the depression of thc key A the con tact or 5.7 is broken, but upon the release 't0 of the key and its return to original position this contact. is again made and the .current coming from the hatterv M goes through the key A, the contacts 56. 57, the line F through the drum solenoid 80 thence through the line Fto the contacts '192.y bridge piece 197 and the contact'193 (which is diagrammaticall)v illustrated in Fig. 1G) thence through the line F to the battery.

v'.Whcn the switch 190 is thrown into. posi it) tion for duplication the 4bridge piece 197 is removed from the contacts 192 and 193 and the' contacts 194 and 195 are bridged by the member 19S. it will thus be observed that the circuit through the drum solenoid is -brokcn but that the circuit through the drum D is so made that when the actuators carried .4 by' said .drum cross the 'contact members 33 and 34 the current n'ill be permitted to travel through the solcnoids The course of the 80 current in such instance is as follows: leading,r from the battery M along the conductor G to the drinn D. the contacts 33a, and 34a 1ulrich are closed by the actuator on the drum 'through the line a' to the terminals 203 ahich are closed by the bridge 206 thence through the line a2 to the solenoid which actuates the return key and inally through ine a3 to the battery.

The. circuits for the line and half line stl keys-are similar to those of the return key except. that the two solenoids which operate the line and half line key have a common return conductor. Upon depression of the 'linekey B the course of the circuit is as fol- 4Q .1ovvs"(Fig. 16').V From'battery M through -key :B contacts 172,"return B2. 4.Forduplication' the circuit l of the line key is as 'folio-ws; battery M through line Gr, '-or. ground, to drum D,

The circuits'forthe half line key are as i follows: upondepression of the key C from i6 battery-.M,'through key C contacts 180C, 181",

' line` C to solenoid 173 and thence through the common return circuit B2, C2 to battery.

For duplicationthe current for 'the half line key is from battery M through line G or 4ground to drum D through contact's 33,
